Nano-antioxidants prove their potential
Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.
New method of incorporating fluoride into drugs
German scientists solve nonclassical 2-norbornyl carbocation structure
The quantum secret to alcohol reactions in space
Chemists have discovered that an 'impossible' reaction at cold temperatures actually occurs with vigour, which could change our understanding of how alcohols are formed and destroyed in space.
Exposure to air transforms gold alloys into catalytic nanostructures
(Phys.org) —Gold bars may signify great wealth, but the precious metal packs a much more practical punch when shrunk down to just billionths of a meter. Unfortunately, unlocking gold's potential often requires ...
Team uncovers fundamental property of astatine, rarest atom on Earth
An international team of scientists, including a University of York researcher, has carried out ground-breaking experiments to investigate the atomic structure of astatine (Z=85), the rarest naturally occurring ...
Power behind primordial soup discovered
(Phys.org) —Researchers at the University of Leeds may have solved a key puzzle about how objects from space could have kindled life on Earth.
Thinnest graphene sheets react strongly with hydrogen atoms; thicker sheets are relatively unaffected
(Phys.org)—Single sheets of graphene, a curious material only 1 atom thick, are 100 times more chemically reactive than double or triple sheets, Stanford scientists say in a new paper published online Jan. ...
'Molecular levers' may make materials better
(Phys.org)—In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could ...
Physicists achieve elusive 'evaporative cooling' of molecules
Achieving a goal considered nearly impossible, JILA physicists have chilled a gas of molecules to very low temperatures by adapting the familiar process by which a hot cup of coffee cools.
Hydrogen fuel cell for phone charging set for 2013
New driving force for chemical reactions discovered
New research just published in the journal Science by a team of chemists at the University of Georgia and colleagues in Germany shows for the first time that a mechanism called tunneling control may drive chemical reacti ...
Replacing hydrogen in fluorescent dyes improves detection ability, stability and shelf life
By swapping out one specific hydrogen atom for an isotope twice as heavy, researchers have increased the shelf life and detection ability of fluorescent probes that are essential to studying a variety of inflammatory ...
Study shows adding UV light helps form 'Missing G' of RNA building blocks
For scientists attempting to understand how the building blocks of RNA originated on Earth, guanine -- the G in the four-letter code of life -- has proven to be a particular challenge. While the other three ...
